Seeking Old Recipe- Zucchini Quiche w/ Sour Cream;Craig Claiborne

After many hours of searching through folders, I am posting here to ask for help.

This Craig Claiborne book was likely done in the late 70's-early '80's. It was not a NYTimes cookbook It may have had yoghurt, but i think it was sour cream.It didn't have any meat. iirc the zucchini was sliced, not grated. I really appreciate your time on this.
